Yes, there have been many updates between 0.20-fixes and current SVN
trunk. SVN trunk is currently at schema version 1191
(http://cvs.mythtv.org/trac/browser/trunk/mythtv/libs/libmythtv/dbcheck.cpp)
whilst 0.20-fixes is at version 1160
(http://cvs.mythtv.org/trac/browser/branches/release-0-20-fixes/mythtv/libs/libmythtv/dbcheck.cpp)

You can always upgrade a database from an older version of MythTV to a
later version, but you cannot do this process in reverse (*) - once
you upgrade your version of MythTV, your database may no longer be
compatible with older versions. The upgrade process is automatic, but
it's always sensible to take a backup of the database before upgrading
to a newer version of MythTV.
(*) It may be possible to manually alter the database to reset tables
to their old settings in order to downgrade the DB schema, but this is
neither recommended nor supported.
